iPhone and iPod Touch Jailbreak Software

The iPhone Dev-Team has released RedSn0w 0.9.9b5 – an official tethered jailbreak for iOS 5. Users don’t have to point to downloaded iOS 5 ipws any more. Just run and jailbreak.

Currently only the Mac version has been made available. Windows version is coming soon. However Windows users can still jailbreak iOS 5 with Redsn0w 0.9.9.b4, – just go to “Extras” -> “Select IPWS” and select your iOS 5 ipsw file (can download here).

Good news for users who need carrier unlock (ultrasn0w or Gevey Sim). With RedSn0w 0.9.9b5 you can update to iOS 5 and preserve the baseband (modem) version for unlock:

The new “Custom IPSW” button on the Extras screen will create a custom IPSW without the baseband update for 4.3.3 or 5.0gm (iPhone3GS and iPhone4 only, for now). Remember not to accidentally restore to the stock IPSW after you create the custom one! The custom one begins with NO_BB_ (for “no baseband”).

You must enter “Pwned DFU” mode before trying to use the NO_BB_ IPSW with iTunes (and your hosts file cannot be pointing to Cydia’s servers due to the new blob nonce mechanism they’re using in iOS5).

The iPhone Dev team has just released the second beta of their untethered RedSn0w jailbreak (the first beta has been released few hours ago and has more bugs).

New jailbreak is called “Jailbreak Monte”, as it uses new “backup method”. The iPhone Dev Team warns that their beta-version is not a general release and you should back up all your media before using it. There are also other limitations and bugs:

The team asks not to participate in testing if you rely on the ultrasn0w carrier unlock;

The bluetooth functionality is disabled due to sandbox problem;

iPod player works only on iPod touch 4G;

To use this version of jailbreak Cydia should have your 4.2b3 SHSH blobs saved on file and following:

“You must already have the usbmuxd software installed and running on your Mac (this requirement will eventually go away too). The correct invocation of the relay is just as that page says: “./tcprelay.py -t 22:2222”. If the relay isn’t installed or running correctly by the time the redsn0w ramdisk has started, you’ll need to restore to stock FW again to try it again. Please test it beforehand to save yourself some time!”

Now, if you’re ready to apply this version of jailbreak, upi can download redsn0w 0.9.7 beta here.

After downloading and applying just select “Jailbreak Monte” to try out the untether.

The iPhone Dev team asks to test it after a fresh restore in order to keep track of the variables involved. Be careful!

By the way, iPodUplink has posted a video where you can see how to jailbreak your device with the latest version of redsn0w:

If you have an iPhone 3GS with the new bootrom you will only be able to perform a tethered jailbreak at this time. This means you will need Redsn0w’s assistance to boot into your jailbroken device.

IMPORTANT FOR UNLOCKERS
During this process you can update your baseband to the 06.15 version. If you are on 05.14 or 05.15 or higher you will need to do this to unlock. You do not need to do this for jailbreak only. Please read the following very carefully before deciding whether to do this.

There is no way to come back down from baseband 06.15, and there’s no hiding the baseband version from Apple. You’ll be voiding your warranty in a very obvious way.

If some future baseband comes out with a critical fix, you won’t be able to update to it if it remains down in the 05.xx sequence (then again, you wouldn’t update to it if you wanted to keep your unlock anyway).

Starting with FW 4.2.1 if you have 06.15 on your iPhone you won’t ever be able to restore to stock firmware (it will fail). You’ll need to only restore to custom IPSWs (then again, if you’re unlocker you should already be doing that).

Don’t update to 06.15 if you don’t need to, you can just jailbreak without unlocking using this tutorial! Only update baseband if you need the unlock and you’re stuck on baseband version 05.14 or 05.15, and you’re willing to assume the above risks. You can find out your baseband version in Settings -> General -> About -> Modem Firmware.

Those with an unlockable baseband and on a lower firmware should use PwnageTool instead to update without upgrading your baseband.

Step One
Create a folder on your desktop called Pwnage

Download RedSn0w from here or here. Save it in the Pwnage folder. Likewise, download the latest 4.2.1 firmware from below and place it in the same folder.

UPDATE2: If you have 05.13 baseband or lower – do not update to 4.2.1, use PwnageTool to create custom firmware!

This is step-by-step instructions on how to jailbreak and unlock your iPhone 3G on iOS 4.2.1 firmware using RedSn0w 0.9.6b5 for Windows.

During this process you can update your baseband to the 06.15 version. If you are on 05.14 or 05.15 or higher you will need to do this to unlock. You do not need to do this for jailbreak only. Please read the following very carefully before deciding whether to do this.

Step One
Create a folder on your desktop called Pwnage

Download RedSn0w from here or here. Save it in the Pwnage folder. Likewise, download the latest 4.2.1 firmware from below and place it in the same folder.

Run RedSn0w and point it at the 4.0 IPSW. (Yes – point it at the 4.0 IPSW even though you’re at 4.0.2). This will also hacktivate your iPhone3G at 4.0.1 if you haven’t already been activated by iTunes.

If you need a carrier unlock – install ultrasn0w in Cydia (add repository http://repo666.ultrasn0w.com). For T-Mobile in the USA remember to turn off 3G mode in Settings→General→Network.
